DESCRIPTION

This manual can be used for both internal and external backwashing Full Auto

options.

Reference

Reference Control Philosophy (DOQ0000138-EN) and Sequence Diagram

(DOQ0000139-EN) for additional details on full-auto control programming. For

Semi-Auto options, reference IB Logic Diagram (DOQ0000159-EN) or EB Logic

Diagram (DOQ0000164-EN) for additional details.

Internal Backwash

The Internal Backwash sequence will take each Filter Station offline in sequence.

The Drain Valve will energize at the first Filter Station allowing the inlet of the

station to be connected to the Drain Header of the unit. Cleaning fluids are then

diverted from the Outlet Header to dislodge and discharge accumulated debris

collected on the outside of the Filter Element. The Filter Station is then placed

back online, and after a short pause, the sequence continues to the remaining

Filter Stations.

External Backwash

The External Backwash sequence will take each Filter Station offline in

sequence. The Drain Valve and Backwash will energize at the first Filter Station

allowing the inlet of the station to be connected to the Drain Header, and the

outlet of the station to be connected to the Backwash Header of the unit. The

Backwash Supply Valve will then open to supply cleaning fluid to the Backwash

Header. Cleaning fluids are then diverted from the Backwash Header to dislodge

and discharge accumulated debris collected on the outside of the Filter Element.

The Filter Station is then placed back online, and after a short pause, the

sequence continues to the remaining Filter Stations.

The system is controlled by an industrial controller housed in a NEMA rated

enclosure. An HMI touch panel display is used to communicate with the

controller.

MAIN SCREEN

The top of the main screen (Images 1 and 2) will display the status states of the

filter (Table 1). When the timed backwash function is activated it will show a

countdown to the next backwashing cycle in minutes. If the Backwash Interval

time setting is set to zero, this timer will be disabled and the TIMED BACKWASH

DISABLED message will be displayed (Image 6). If a manual or differential

pressure backwash cycle is performed the time interval will reset to the

Backwash Interval time setting. Below is a description of each button function on

the main screen.

A. The ON/OFF power button – See warning box on the first

page. Turns the PLC ON and OFF. In the event of power failure, the

operator will have to turn the system back ON. To reset the system and

clear all error messages, turn the system OFF and back ON.

B. BACKWASH button – Allows the operator to initiate a manual

backwashing sequence. When the button is touched, BACKWASHING will

be displayed in the status box.

C. PARAMETER ADJUST button – Touching this button will display the

parameter adjustment screen. This is where changes can be made to the

backwash sequences (Image 3 for Internal Backwash, Image 4 for

External Backwash).

(Image 7).

PARAMETER ADJUSTMENTS

Parameter adjustments can be made by touching the button at the right of the

field you want to change. The numeric keypad (Image 5) will appear and allow

you to enter a new parameter. The range that can be entered will be displayed.

Below is a description of each button function on the Parameter Adjustment

screen (Image 3 for Internal. Image 4 for External).

A. BACKWASH INTERVAL (M) – The Backwash Interval is the amount of

time between automatic backwashing cycles. Backwash sequences will

automatically occur based on this time. Units are in minutes and it is

preset to 240 minutes. Range is 0-1440 minutes. Setting this value to

zero (0) will disable the timed backwash function. (See Image 6).

B. BACKWASH DURATION (S) – The Backwash Duration is the amount of

time each station backwashes during a backwashing sequence. Units are

in seconds and it is preset to 10 seconds. Range is 0-30 seconds.

C. BACKWASH WARNING (S) – Backwash Warning is the delay between

the backwash sequence request and the start of valves actuation. The

backwash in process relay (RL2) is energized to indicate the sequence

will start. Units are in seconds and is preset to 2 seconds. Range is 0-90

seconds.

D. STATION PAUSE (S) – Station Pause is the pause between stations

during the backwashing sequence. Units are in seconds and it is preset to

2 seconds. Range is 0-30 seconds.

E. DP START DELAY (S) – DP Start Delay is the amount of time the signal

from the differential pressure switch must be present prior to initiating a

backwashing sequence. Units are in seconds and is preset to 5 seconds

Range is 0-30 seconds.

F. BACKWASH START DELAY (S)– (EXTERNAL backwashing systems

only) Backwash Start Delay is the amount of time between taking a

station offline and opening the backwash supply valve. This delay allows

the process fluid to drain from the filter body. Units are in seconds and is

preset at 2 seconds. Range is 0-30 seconds.

G. STATION DRAIN (S)– (EXTERNAL backwashing systems only). The

Station Drain duration is the amount of time between closing the

backwash supply valve and placing the station back online. This delay

allows the backwash fluid to drain from the filter body. Units are in

seconds and is preset at 2 seconds. Range is 0-30 seconds.

H. MAIN SCREEN button – Touching this button will return the user to the

Main Screen (Image 1 or 2).

I. STATION STATUS button – Touching this button will display the station

adjustment screen. This is where stations may be enabled or disabled.

(Image 7)

STATION STATUS

The Station Status screen (Image 7) allows the operator to add or remove

individual stations from the backwash sequence. Pressing the button for the

station to be modified will turn that station ON or OFF. Stations that are ON will

be included in the backwash sequence; stations that are OFF are not included

(skipped). Pressing Next Screen or Back Screen button will cycle to the next or

previous set of stations (when it applies).

FAULT MESSAGES

Below is a description of each fault message on the HMI operator interface. To

reset the system and clear all fault messages and outputs, turn the system OFF

and back ON. The System Fault Relay (RL-1) will be de-energized when a fault

is present.

A. HIGH DP – When the system initiates four backwashing cycles due to

differential pressure within 60 minutes, a fault is set and the message

HIGH DP (Image 8) will be indicated on display. Backwash sequences will

occur as normal. Possible causes: plugged elements, insufficient

backwash duration or insufficient inlet pressure to properly backwash the

element.

DIFFERENTIAL PRESSURE SWITCH ADJUSTMENT

The differential pressure switch senses a difference in pressure between the inlet

and outlet piping. When the factory pressure preset has been reached, it triggers

a backwashing sequence. The factory preset is 15 PSID (1 bar).

To adjust the preset, remove the DP switch cover and turn the hex-adjusting nut.

Turn it clockwise to decrease the allowable differential pressure between the inlet

and outlet piping. Turn the hex nut counterclockwise to increase the allowable

differential pressure between the inlet and outlet piping. One flat turn (1/6th of a

turn) of the hex-adjusting nut changes the setting by approximately 2 PSID (0.14

bar).

CUSTOMER INTERFACE

A. GENERAL FAULT (RL-1) – This relay is energized during normal

operation. It will de-energize to indicate power loss, system is OFF or if an

HIGH DP condition is present (if there are four differential pressure clean

sequences in 60 minutes). See electrical schematic for connection details.

B. BACKWASH IN PROCESS (RL-2) – This relay is energized when the

system is cleaning (backwashing). Reference the electrical schematic for

contact connections.

C. REMOTE BACKWASH SWITCH – Use a momentary normally open dry

contact across the Remote Backwash terminals to initiate a backwash.

Reference the electrical schematic for contact connections.
